Description

Rail transit passenger compartment door for preventing hand pinching

Technical Field

The utility model relates to a rail transit passenger compartment door, in particular to a rail transit passenger compartment door which can avoid pinching hands.

Background Art

Rail transit doors are usually equipped with recessed handles, which can be used by attendants or passengers to open and close the doors when necessary. In order to improve the passability of passengers getting on and off the train, the door opening is usually designed to be maximized. In this case, after the door is opened, the handle will move to the inside of the vehicle cover. For this fixed recessed handle, passengers will inevitably subconsciously put their hands into the handle, and during the door opening process, they are easily pinched and cause personal injury.

Summary of the invention

The utility model aims to provide a rail transit passenger compartment door which can avoid pinching hands, so as to solve the above technical problems.

To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rail transit passenger compartment door that avoids hand pinching, comprising door panels, seams, doors and windows, mounting groove one, a hand buckle box, a hand buckle groove, a spring A, a limit groove A, a limit groove B, a spring reset angle, and an anti-pinch buckle. The seams are respectively installed at the inner ends of the left and right door panels, the door windows are installed on the upper part of the door panels, the mounting groove one is opened in the middle of the front end of the door panels, the hand buckle box is installed in the mounting groove one, the hand buckle groove is opened in the middle of the front end of the hand buckle box, the spring A is installed at the rear end of the hand buckle groove, the limit groove A is opened at the front of the left and right ends of the hand buckle groove, the limit groove B is opened at the rear of the left and right ends of the hand buckle groove, the spring reset angle is elastically connected to the front end of the limit groove B, and the anti-pinch buckle is installed in the hand buckle groove through the spring A.

On the basis of the above technical scheme, the anti-pinch buckle includes a pressing plate, a slider, a second mounting slot, a limit buckle, and a spring B. The shape of the pressing plate corresponds to the hand buckle slot. The slider is fixed to the rear end of the pressing plate, and the slider is elastically connected to the hand buckle slot through the front end elastic force of the spring A. The second mounting slot is horizontally opened in the middle of the slider. The two rear ends of the limit buckles are respectively hinged to the left and right parts of the second mounting slot. The spring B is elastically connected to the inner ends of the left and right limit buckles, and the front end of the limit buckle slides forward under the extrusion of the spring B and is limited to the limit slot A or the limit slot B. When the front end of the limit buckle is limited to the limit slot A, the pressing plate is flush with the front end of the hand box.

Based on the above technical solution, the limit buckle or extrusion spring reset angle abuts against the limit groove B.

Compared with the prior art, the utility model has the following advantages: the utility model realizes that the buckle is flush and hidden under normal conditions by installing an anti-pinch buckle connected by a spring on the concave buckle installed on the rail transit passenger compartment door, and cooperates with the limit groove opened by the buckle, so that the buckle can be pressed and locked when in use, which does not affect the use and prevents passengers from subconsciously putting their hands into the buckle and causing pinching injuries.

DETAILED DESCRIPTION

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 1 to 5, a rail transit passenger compartment door for preventing fingers from being pinched comprises a door panel 1, a seam 2, a door window 3, a mounting groove 4, a hand box 5, a hand groove 6, a spring A7, a limiting groove A8, a limiting groove B9, a spring reset angle 10, and an anti-pinch buckle 11. The seams 2 are respectively installed at the inner ends of the left and right door panels 1, the door window 3 is installed on the upper part of the door panel 1, the mounting groove 4 is opened in the middle of the front end of the door panel 1, the hand box 5 is installed in the mounting groove 4, the hand groove 6 is opened in the middle of the front end of the hand box 5, the spring A7 is installed at the rear end of the hand groove 6, the limiting groove A8 is opened at the front of the left and right ends of the hand groove 6, the limiting groove B9 is opened at the rear of the left and right ends of the hand groove 6, the spring reset angle 10 is elastically connected to the front end of the limiting groove B9, and the anti-pinch buckle 11 is installed in the hand groove 6 through the spring A7.

The anti-pinch buckle 11 includes a pressing plate 12, a slider 13, a second mounting groove 14, a limit buckle 15, and a spring B16. The shape of the pressing plate 12 corresponds to the hand buckle groove 6. The slider 13 is fixed to the rear end of the pressing plate 12, and the slider 13 is elastically connected to the hand buckle groove 6 through the front end elastic force of the spring A7. The second mounting groove 14 is horizontally opened in the middle of the slider 13. The rear parts of the two limit buckles 15 are respectively hinged to the left and right parts of the second mounting groove 14. The spring B16 is elastically connected to the inner ends of the left and right limit buckles 15, and the front end of the limit buckle 15 slides forward under the extrusion of the spring B16 and is limited to the limit groove A8 or the limit groove B9, and when the front end of the limit buckle 15 is limited to the limit groove A8, the pressing plate 12 is flush with the front end of the hand buckle box 5.

The limiting buckle 15 or the extrusion spring reset angle 10 abuts against the limiting groove B9.

The working principle of the utility model is as follows: in normal state, the pressing plate 12 is limited by the limiting buckle 15 to be flush with the front end of the hand box 5 in the limiting groove A8, which does not attract the attention of passengers and avoids accidental pinching when the hand is subconsciously stretched out. When the attendant or the passenger needs it, the pressing plate 12 presses the slider 13 to squeeze the spring A7 to move backward, and the limiting buckle 15 turns inward and squeezes the spring B16 as it disengages from the limiting groove A8. When it slides to the limiting groove B9 at the rear, the spring B16 pushes out the limiting buckle 15, and the front end of the limiting buckle 15 is limited to the limiting groove B9, so that the hand box 5 exposes the hand groove 6 for temporary door opening and closing. When resetting, continue to press the pressing plate 12 to the bottom, the limiting buckle 15 is pressed to the rear side of the spring reset angle 10, and the spring reset angle 10 is squeezed against the front end of the limiting groove B9, release the pressing plate 12, and the spring A7 pushes the slider 13 forward to reset the pressing plate 12. Under the maintenance of the spring reset angle 10, the front end of the limiting buckle 15 misses the limiting groove B9 and enters the limiting groove A8 for limiting.

The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
